Kinetic operator effects in B-> X_c l nu at O(alpha_s)

Alberti, Andrea, Ewerth, Thorsten, Gambino, Paolo et al.

Understand

We compute the O(alpha_s) corrections to the Wilson coefficient of the kinetic operator in inclusive semileptonic B decays.

Our analytic calculation agrees with reparameterization invariance and with previous numerical results and paves the way to the calculation of analogous corrections to other power-suppressed coefficients.
